Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting technology, and in particular to a suction cup assembly and a fruit and vegetable sorting device. Background Technology

[0002] Currently, fruits and vegetables are a type of food that people often consume. Fruits and vegetables include cherries, apples, pears, and tomatoes, among others. After ripening, fruits and vegetables need to be harvested and then transported to factories for sorting and processing to facilitate subsequent packaging and sales.

[0003] In related technologies, fruit and vegetable sorting devices may include suction cup assemblies. The suction cup assemblies are used to contact fruits and vegetables and create negative pressure on the surface of the fruits and vegetables so that the suction cup assemblies can adhere to the surface of the fruits and vegetables so that the suction cup assemblies can adsorb the fruits and vegetables. Then the suction cup assemblies can pick up the fruits and vegetables and transfer them to a designated location.

[0004] However, different fruits and vegetables are of different sizes. Smaller suction cup components cannot provide enough suction force to pick up larger fruits and vegetables, while larger suction cup components cannot reach the surface of smaller fruits and vegetables. This results in different models of suction components in fruit and vegetable sorting devices for different sizes of fruits and vegetables, making it difficult to use the same suction components. Utility Model Content

[0005] The present invention aims to provide a suction cup assembly and a fruit and vegetable sorting device to solve the technical problem that the adsorption components in the existing fruit and vegetable sorting devices for different sizes are of different models and the adsorption components are difficult to be universal.

[0006] The technical problem solved by this utility model embodiment is addressed by the following technical solution:

[0007] A suction cup assembly is provided, comprising:

[0008] The main body has an air intake chamber.

[0009] An inner suction cup is installed on the main body, and the inner suction cup has a first suction cavity, and the suction cavity is connected to the first suction cavity;

[0010] An outer suction cup is installed on the main body and is arranged around the inner suction cup. A second suction cavity is formed between the outer suction cup and the inner suction cup, and the suction cavity is connected to the second suction cavity.

[0011] With the above structure, the size of the inner suction cup can be adapted to smaller fruits and vegetables, so that when the suction cup assembly adsorbs smaller fruits and vegetables, the end of the inner suction cup facing away from the main body can contact the fruits and vegetables; the end of the main body facing away from the inner suction cup can be connected to an air suction machine, which can suck air into the suction chamber, so that the gas in the first adsorption chamber is removed, and a negative pressure is generated between the cavity wall of the first adsorption chamber and the surface of the fruits and vegetables, so that the cavity wall of the first adsorption chamber adheres tightly to the surface of the fruits and vegetables, and the inner suction cup adsorbs the fruits and vegetables.

[0012] The size of the outer suction cup can be adapted to larger fruits and vegetables, so that when the suction cup assembly adsorbs larger fruits and vegetables, the end of the inner suction cup facing away from the main body and the end of the outer suction cup facing away from the main body can simultaneously contact the fruits and vegetables. The end of the main body facing away from the outer suction cup can be connected to an air suction machine, which can suck air into the suction chamber, so that the gas in the second adsorption chamber is removed. A negative pressure is generated between the cavity wall of the second adsorption chamber and the surface of the fruits and vegetables, so that the cavity walls of the first adsorption chamber and the cavity walls of the second adsorption chamber are pressed tightly against the surface of the fruits and vegetables, and the inner and outer suction cups adsorb the fruits and vegetables.

[0013] In some embodiments, the central axis of the inner suction cup is collinear with the central axis of the outer suction cup, and the end of the outer suction cup facing away from the main body protrudes relative to the end of the inner suction cup facing away from the main body.

[0014] With the above structure, the end of the outer suction cup facing away from the main body protrudes relative to the end of the inner suction cup facing away from the main body. When the suction cup assembly adsorbs larger fruits and vegetables, the protruding part of the outer suction cup relative to the inner suction cup can first contact the fruits and vegetables, and the cavity wall of the second suction chamber can first adhere to the fruits and vegetables. Subsequently, the end of the inner suction cup facing away from the main body can contact the fruits and vegetables, and the cavity wall of the first suction chamber can also adhere to the fruits and vegetables, so that the suction cup assembly can more stably adsorb larger fruits and vegetables, thereby preventing larger fruits and vegetables from falling off the suction cup assembly.

[0015] In some embodiments, the wall of the first adsorption chamber includes a first inner groove, the first inner groove surrounding the central axis of the first adsorption chamber.

[0016] With the above structure, during the adsorption of fruits and vegetables by the suction cup assembly, the end of the cavity wall of the first adsorption chamber facing away from the main body first contacts the surface of the fruits and vegetables. Then, the air suction machine can suck air into the suction chamber so that the gas in the first adsorption chamber is removed. The groove wall of the first inner groove can be folded to discharge the gas in the first adsorption chamber to a greater extent, so that the inner suction cup can adsorb fruits and vegetables more stably.

[0017] In some embodiments, there are multiple first inner grooves, and all the first inner grooves are arranged sequentially along the extension direction of the central axis of the first adsorption cavity.

[0018] With the above structure, there are multiple first inner grooves. During the process of the air suction machine sucking air into the suction chamber, all the first inner grooves can be folded at the same time, so that the inner suction cup can quickly retract and quickly adsorb the surface of fruits and vegetables, thereby improving the working efficiency of the suction cup assembly.

[0019] In some embodiments, the wall of the second adsorption chamber includes a second inner groove, which is formed in the outer suction cup and surrounds the central axis of the second adsorption chamber.

[0020] With the above structure, during the adsorption of fruits and vegetables by the suction cup assembly, the end of the cavity wall of the second adsorption chamber facing away from the main body first contacts the surface of the fruits and vegetables. Then, the air suction machine can suck air into the suction chamber so that the gas in the second adsorption chamber is removed. The groove wall of the second inner groove can be folded to discharge the gas in the second adsorption chamber to a greater extent, so that the outer suction cup can adsorb fruits and vegetables more stably.

[0021] In some embodiments, there are multiple second inner grooves, and all the second inner grooves are arranged sequentially in the extension direction of the central axis of the second adsorption cavity.

[0022] With the above structure, there are multiple second inner grooves. During the process of the air suction machine sucking air into the suction chamber, all the second inner grooves can be folded at the same time, so that the outer suction cup can be quickly contracted. The outer suction cup and the inner suction cup can work together to quickly adsorb the surface of fruits and vegetables, thereby improving the working efficiency of the suction cup assembly.

[0023] In some embodiments, the external suction cup includes a body and a flared portion. One end of the body is mounted to the main body, and the body has a first suction cavity. The flared portion is connected to the end of the body facing away from the main body, and the flared portion surrounds the central axis of the external suction cup. In the direction from the main body to the external suction cup, the cross-sectional area of ​​the flared portion gradually increases. In the extension direction perpendicular to the central axis of the external suction cup, the end of the flared portion facing away from the main body protrudes relative to the periphery of the main body.

[0024] With the above structure, in the extension direction perpendicular to the central axis of the outer suction cup, the end of the flared part facing away from the main body protrudes relative to the periphery of the main body; so that when the suction cup assembly adsorbs larger fruits and vegetables, the flared part can have a larger contact area with the surface of the fruits and vegetables, so that the pressure between the flared part and the surface of the fruits and vegetables is greater, and the suction cup assembly can adsorb fruits and vegetables more stably.

[0025] In some embodiments, the suction cup assembly further includes:

[0026] A limiting block is connected to one end of the main body facing away from the inner suction cup;

[0027] A first connector is sleeved on the outer surface of the main body and is movably mounted on the main body;

[0028] The second connector is sleeved on the outer surface of the main body and is movably installed on the main body; the first connector and the second connector are arranged in sequence in the direction from the limiting block to the inner suction cup.

[0029] With the above structure, both the first connector and the second connector can be fixed to the frame of the fruit and vegetable sorting device. The main body can move relative to the first connector and the second connector. Both the first connector and the second connector can guide the main body so that after the inner suction cup and the outer suction cup adsorb the fruit and vegetables, the main body can move vertically and pick up the fruit and vegetables through the inner suction cup and the outer suction cup.

[0030] In some embodiments, the suction cup assembly further includes:

[0031] An elastic reset element is connected between the limiting block and the first connecting element.

[0032] With the above structure, the elastic reset component is connected between the limiting block and the first connecting component. The elastic reset component can provide elastic force when the main body descends to reduce the impact force when the inner suction cup and the outer suction cup come into contact with fruits and vegetables, so as to avoid the fruits and vegetables being crushed. After the inner suction cup and the outer suction cup adsorb fruits and vegetables, the main body can quickly rebound, improving the working efficiency of the suction cup assembly.

[0033] Compared with existing technologies, the size of the inner suction cup can be adapted to smaller fruits and vegetables, so that when the suction cup assembly adsorbs smaller fruits and vegetables, the end of the inner suction cup facing away from the main body can contact the fruits and vegetables; the end of the main body facing away from the inner suction cup can be connected to an air suction machine, which can suck air into the suction chamber, so that the gas in the first adsorption chamber is removed, and a negative pressure is generated between the cavity wall of the first adsorption chamber and the surface of the fruits and vegetables, so that the cavity wall of the first adsorption chamber adheres tightly to the surface of the fruits and vegetables, and the inner suction cup adsorbs the fruits and vegetables.

[0034] The size of the outer suction cup can be adapted to larger fruits and vegetables, so that when the suction cup assembly adsorbs larger fruits and vegetables, the end of the inner suction cup facing away from the main body and the end of the outer suction cup facing away from the main body can simultaneously contact the fruits and vegetables. The end of the main body facing away from the outer suction cup can be connected to an air suction machine, which can suck air into the suction chamber, so that the gas in the first and second suction chambers is removed. A negative pressure is generated between the cavity walls of the first and second suction chambers and the surface of the fruits and vegetables, so that the cavity walls of the first and second suction chambers are pressed tightly against the surface of the fruits and vegetables, and the inner and outer suction cups adsorb the fruits and vegetables.

[0047] With the above structure, the size of the inner suction cup 20 can be adapted to smaller fruits and vegetables, so that when the suction cup assembly 100 adsorbs smaller fruits and vegetables, the end of the inner suction cup 20 facing away from the main body 10 can contact the fruits and vegetables; the end of the main body 10 facing away from the inner suction cup 20 can be connected to an air pump, such as an air pump, which can draw air into the air chamber 102, so that the gas in the first adsorption chamber 202 is removed, and a negative pressure is generated between the cavity wall of the first adsorption chamber 202 and the surface of the fruits and vegetables, so that the cavity wall of the first adsorption chamber 202 is pressed tightly against the surface of the fruits and vegetables, and the inner suction cup 20 adsorbs the fruits and vegetables.

[0048] The size of the outer suction cup 30 can be adapted to larger fruits and vegetables, so that when the suction cup assembly 100 adsorbs larger fruits and vegetables, the end of the inner suction cup 20 facing away from the main body 10 and the end of the outer suction cup 30 facing away from the main body 10 can simultaneously contact the fruits and vegetables. The end of the main body 10 facing away from the outer suction cup 30 can be connected to an air suction machine, which can suck air into the air suction chamber 102, so that the gas in the first adsorption chamber 202 and the second adsorption chamber 302 is removed. A negative pressure is generated between the cavity wall of the first adsorption chamber 202 and the cavity wall of the second adsorption chamber 302 and the surface of the fruits and vegetables, so that the cavity walls of the first adsorption chamber 202 and the cavity walls of the second adsorption chamber 302 are pressed tightly against the surface of the fruits and vegetables, and the inner suction cup 20 and the outer suction cup 30 jointly adsorb the fruits and vegetables.

[0049] Specifically, in this embodiment, the main body 10 can be a long cylindrical structure, the suction chamber 102 can be cylindrical, the suction chamber 102 can pass through the opposite ends of the main body 10, and the central axis of the suction chamber 102 is collinear with the central axis of the main body 10; in the extension direction perpendicular to the central axis of the main body 10, the cross-section of the inner suction cup 20 can be circular at all points, and the cross-section of the outer suction cup 30 can also be circular at all points.

[0051] In some embodiments, the central axis of the inner suction cup 20 is collinear with the central axis of the outer suction cup 30, and the end of the outer suction cup 30 facing away from the main body 10 protrudes relative to the end of the inner suction cup 20 facing away from the main body 10.

[0052] With the above structure, the end of the outer suction cup 30 facing away from the main body 10 protrudes relative to the end of the inner suction cup 20 facing away from the main body 10. When the suction cup assembly 100 adsorbs larger fruits and vegetables, the protruding part of the outer suction cup 30 relative to the inner suction cup 20 can first contact the fruits and vegetables, and the cavity wall of the second suction cavity 302 can first adhere to the fruits and vegetables. Subsequently, the end of the inner suction cup 20 facing away from the main body 10 can contact the fruits and vegetables, and the cavity wall of the first suction cavity 202 can also adhere to the fruits and vegetables, so that the suction cup assembly 100 can more stably adsorb larger fruits and vegetables, thereby preventing larger fruits and vegetables from falling off the suction cup assembly 100.

[0053] Specifically, in this embodiment, the portion of the outer suction cup 30 that protrudes relative to the inner suction cup 20 can be a circular flared shape. In other embodiments, the portion of the outer suction cup 30 that protrudes relative to the inner suction cup 20 can also be other shapes, such as a rectangular flared shape.

[0054] Please refer to Figure 3 In some embodiments, the cavity wall of the first adsorption cavity 202 includes a first inner groove 204, which surrounds the central axis of the first adsorption cavity 202.

[0055] With the above structure, during the adsorption of fruits and vegetables by the suction cup assembly 100, the end of the cavity wall of the first adsorption chamber 202 facing away from the main body 10 first contacts the surface of the fruits and vegetables. Then, the air pump can draw air into the air chamber 102 so that the gas in the first adsorption chamber 202 is removed. The groove wall of the first inner groove 204 can be folded to discharge the gas in the first adsorption chamber 202 to a greater extent, so that the inner suction cup 20 can adsorb fruits and vegetables more stably.

[0056] Specifically, in this embodiment, the groove wall of the first inner groove 204 includes two interconnected inclined walls, such that the cross-section of the first inner groove 204 first increases and then decreases in the direction from the main body 10 to the inner suction cup 20.

[0057] In other embodiments, the groove wall of the first inner groove 204 may also be other shapes, such as a smooth arc surface.

[0058] In some embodiments, there are multiple first inner grooves 204, and all the first inner grooves 204 are arranged sequentially in the extension direction of the central axis of the first adsorption cavity 202.

[0059] With the above structure, there are multiple first inner grooves 204.

[0062] In some embodiments, the cavity wall of the second adsorption cavity 302 includes a second inner groove 3202, which is formed in the outer suction cup 30 and surrounds the central axis of the second adsorption cavity 302.

[0063] With the above structure, during the adsorption of fruits and vegetables by the suction cup assembly 100, the end of the cavity wall of the second adsorption chamber 302 facing away from the main body 10 first contacts the surface of the fruits and vegetables. Then, the air pump can draw air into the air chamber 102 so that the gas in the second adsorption chamber 302 is removed. The groove wall of the second inner groove 3202 can be folded to discharge the gas in the second adsorption chamber 302 to a greater extent, so that the outer suction cup 30 can adsorb fruits and vegetables more stably.

[0064] Specifically, in this embodiment, the groove wall of the second inner groove 3202 includes two interconnected inclined walls, so that the cross-section of the second inner groove 3202 first increases and then decreases in the direction from the main body 10 to the outer suction cup 30.

[0065] In other embodiments, the groove wall of the second inner groove 3202 may also be other shapes, such as a smooth arc surface.

[0066] In some embodiments, there are multiple second inner grooves 3202, and all the second inner grooves 3202 are arranged sequentially in the extension direction of the central axis of the second adsorption cavity 302.

[0067] With the above structure, there are multiple second inner grooves 3202. During the process of the air suction machine sucking air into the air suction chamber 102, all the second inner grooves 3202 can be folded at the same time, so that the outer suction cup 30 can be quickly contracted. The outer suction cup 30 and the inner suction cup 20 can work together to quickly adsorb the surface of fruits and vegetables, thereby improving the working efficiency of the suction cup assembly 100.

[0068] Specifically, in this embodiment, there are three second inner grooves 3202; in the extension direction of the central axis of the second adsorption cavity 302, all the second inner grooves 3202 are evenly distributed on the cavity wall of the entire second adsorption cavity 302.

[0069] In other embodiments, the number of second inner grooves 3202 may be other, such as two or four; all the second inner grooves 3202 may also be located at other positions of the second adsorption cavity 302, for example, all the second inner grooves 3202 are located at the end of the outer suction cup 30 facing the main body 10.

[0070] In some embodiments, the second adsorption chamber 302 is connected to the air intake chamber 102 via the first adsorption chamber 202.

[0071] With the above structure, the second adsorption chamber 302 is connected to the air intake chamber 102 via the first adsorption chamber 202, so that when the same air intake machine draws air into the air intake chamber 102, the gas in the second adsorption chamber 302 and the first adsorption chamber 202 can be quickly and sequentially drawn away, and the inner suction cup 20 and the outer suction cup 30 can quickly and simultaneously contract, and the inner suction cup 20 and the outer suction cup 30 can quickly and stably adsorb the surface of fruits and vegetables.

[0072] Specifically, in this embodiment, the outer suction cup 30 is integrally formed with one end of the main body 10. The outer suction cup 30 can be made of flexible materials such as rubber. The inner suction cup 20 can be glued to one end of the main body 10, and the end of the outer suction cup 30 facing away from the main body 10 protrudes relative to the end of the inner suction cup 20 facing away from the main body 10. The end of the first adsorption cavity 202 facing the main body 10 is connected to the air intake cavity 102, and the end of the second adsorption cavity 302 facing away from the main body 10 is connected to the end of the first adsorption cavity 202 facing away from the main body 10, so that the second adsorption cavity 302 is connected to the air intake cavity 102 through the first adsorption cavity 202.

[0073] In other embodiments, the inner suction cup 20 may also be connected to the body 10 in other ways, such as by integral molding.

[0074] In some embodiments, the outer suction cup 30 includes a body 32 and a flared portion 34. One end of the body 32 is mounted on the main body 10. The body 32 houses the inner suction cup 20, and a second suction cavity 302 is formed between the inner suction cup 20 and the body 32. The flared portion 34 is connected to the end of the body 32 facing away from the main body 10, and the flared portion 34 surrounds the central axis of the outer suction cup 30. In the direction from the main body 10 to the outer suction cup 30, the cross-sectional area of ​​the flared portion 34 gradually increases. In the extension direction perpendicular to the central axis of the outer suction cup 30, the end of the flared portion 34 facing away from the body 32 protrudes relative to the periphery of the body 32.

[0075] With the above structure, in the extension direction perpendicular to the central axis of the outer suction cup 30, the end of the flared portion 34 facing away from the body 32 protrudes relative to the periphery of the body 32; so that when the suction cup assembly 100 adsorbs larger fruits and vegetables, the flared portion 34 can have a larger contact area with the surface of the fruits and vegetables, so that the pressure between the flared portion 34 and the surface of the fruits and vegetables is greater, and the suction cup assembly 100 can adsorb fruits and vegetables more stably.

[0076] Specifically, in this embodiment, the flared portion 34 is circular in the extension direction perpendicular to the central axis of the outer suction cup 30; the flared portion 34 is inclined in the extension direction of the central axis of the outer suction cup 30 so that the cross-sectional area of ​​the flared portion 34 gradually increases in the direction from the main body 10 to the outer suction cup 30.

[0077] In other embodiments, the flared portion 34 may also be in other shapes, such as elliptical or rectangular, in the direction of extension perpendicular to the central axis of the outer suction cup 30.

[0079] With the above structure, the first connector 50 and the second connector 60 can both be fixed to the frame 200 of the fruit and vegetable sorting device. The main body 10 can move relative to the first connector 50 and the second connector 60. The first connector 50 and the second connector 60 can both guide the main body 10 so that after the inner suction cup 20 and the outer suction cup 30 adsorb the fruits and vegetables, the main body 10 can move vertically and pick up the fruits and vegetables through the inner suction cup 20 and the outer suction cup 30.

[0080] Specifically, the limiting block 40 can be a block structure; the first connecting member 50 can include a linear bearing, and the first connecting member 50 can be connected to the frame 200 of the fruit and vegetable sorting device by screws; the second connecting member 60 can have the same structure as the first connecting member 50; the main body 10 can be inserted into the first connecting member 50 and the second connecting member 60.

[0081] In some embodiments, the suction cup assembly 100 further includes an elastic reset member 70, which is connected between the limiting block 40 and the first connector 50.

[0082] With the above structure, the elastic reset member 70 is connected between the limiting block 40 and the first connecting member 50. The elastic reset member 70 can provide elastic force when the main body 10 descends to reduce the impact force when the inner suction cup 20 and the outer suction cup 30 come into contact with fruits and vegetables, so as to avoid the fruits and vegetables being crushed. After the inner suction cup 20 and the outer suction cup 30 adsorb fruits and vegetables, the main body 10 can quickly rebound, improving the working efficiency of the suction cup assembly 100.

[0083] Specifically, the elastic reset member 70 can be a spring. The elastic reset member 70 is sleeved on the main body 10. The upper end of the elastic reset member 70 abuts against the limiting block 40, and the lower end of the elastic reset member 70 abuts against the first connecting member 50.
